SAFETY-PIN.

SPECIFICATION forming part Of Letters Patent NO. 406,367, dated July 2, 1889.

- Application filed November 2'7, 1888 Serial No. 291,982. (No model.)

Tova/ll whom it may concern.-

Be it known that I, EDWARD McGoNNELL, a citizen of the United States, residing at Cape Girardeau, in the county of Cape Gir'ardeau and State of Missouri, have invented certain new and useful Improvements in Safety-Pins, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 represents a side elevation of my improved pin; Fig. 2, a longitudinal sectional view, and Fig. 3 a transverse sectional View.

The invention has relation to certain improvements upon that class of nursery or safety pins which are constructed of a single piece of wire, the wire being formed into two spring-coils, one coil, the longer, serving as the flexible body of the pin, and the other,

the shorter, serving as a retaining sheath or guard for the pointed end of the pin proper, this pin being formed of a continuation of the body-coil, as will more fully hereinafter appear.

The essential objects of the invention are to so improve this class of pins that they will be simple in construction, more durable and effectual in operation, and more easily manufactured than those heretofore made, as will be more fully hereinafter set forth.

The invention will be fully understood from the following description when taken in connection with the annexed drawings.

The pin is constructed of a single piece of wire bent and coiled by means of suitable tools or appliances. A large short coil A is first formed with one end of the wire. A longer and smaller spring coil B is then formed close up against one end of the short coil A. By thus forming the small body-coil B close up against the inner end of the large coil A a crescent-shaped opening or space a is formed for the reception of the sharpened end of the pin 0. This construction also renders the pin stronger and more effectual in operation and easier to manufacture.

- The pin 0 is formed of a continuation of the body-coil B. After the last coil of the body is formed the wire is first extended directly upward a short distance, as at I), (this extended portion 1) lying against the end of the coil,) when it is again bent at c, and turned down to a position approximately parallel with the coils.

Vhen it is desired to close or fasten the pin, the coils are simply distended and the end of the pin inserted in the crescent-opening a in the inner end of the guard-coil A, and when it is desired to disengage the pin from the guard-coil the coils are again distended and the pin permitted to spring out of its own accord.

By thus forming the body or back of a nursery-pin of spring-coils it is obvious that great flexibility is obtained, which property will permit the pin to curve or bend and adjust itself to the conformation of the article to which it is applied, and to accommodate itself to any motion or position of the wearer without pricking or injury.

What I olaim,and desire to secure by Letters Patent, is

1. As an improved article of manufacture, a safety-pin constructed of a single piece of wire, this wire being formed into a large guard-coil A, and a longer flexible body-coil B, this body-coil being of less diameter than the said guard-coil and having its inner end abutting the inner end of the same, whereby the coils are mutually braced, and a crescentshaped opening a is formed for the reception of the point of the securing-pin, and a pin 0,

formed of a continuation of the outer end of ter, thereby bracing the two coils and form-.

ing a crescent-shaped opening for the reception of the securing-pin, and the pins, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWVARD MOCONNELL.
